“…Overexploitation may lead to reduction in effective population size of fish species across the world. Due to this, inbreeding can happen which might result in a deficiency of heterozygotes and deviation from Hardy-Weinberg equilibrium (Beaumont and Hoare 2003). This may be the cause of deficiency of heterozygotes in C. dussumieri, as reduction in landings of the species along with Bombay duck had been reported in Indian waters (Mohan Joseph and Jayaprakash 2003).…”

“…Deviation from Hardy-Weinberg is usually attributed to null alleles (Gopalakrishnan et al 2004;Garcia de Leon et al 1995), selection (Garcia de Leon et al 1995), grouping of gene pools (Walhund effect; Gibbs et al 1997), inbreeding or nonrandom mating (Beaumont and Hoare 2003). Nine of the ten primer pairs in C. dussumieri indicated positive F IS values in different populations.…”

Coilia dussumieri (Valenciennes, 1848) commonly called as golden anchovy, constitutes a considerable fishery in the northern part of both the west and east coasts of India. Despite its clear-cut geographic isolation, the species is treated as a unit stock for fishery management purposes. We evaluated 32 microsatellite primer pairs from three closely related species (resource species) belonging to the family Engraulidae through cross-species amplification in C. dussumieri. Successful cross-priming was obtained with 10 loci, which were sequenced for confirmation of repeats. Loci were tested for delineating the genetic stock structure of four populations of C. dussumieri from both the coasts of India. The number of alleles per locus ranged from 8 to 18, with a mean of 12.3. Results of pairwise F ST indicated genetic stock structuring between the east and west coast populations of India and also validated the utilization of identified microsatellite markers in population genetic structure analysis.

“…These techniques are important in the improvement of fish breeding as they provide a rapid approach for gonadal sterilization, sex control, improvement of hybrid viability and clonation [13]. By manipulating ploidy, sterile, unisex or highly homozygous cohorts of animals can be produced [26].…”

“…Egg activation with untreated spermatozoa then requires diploidization of the haploid zygote by some form of shock to interrupt the first mitotic division [34]. Otherwise, a diploid sperm -the gonad product of a tetraploid male -is needed to fertilise the irradiated egg and produce diploid embryos without further treatment [26].…”

Due to the increase in growth rate of the world population, the demand for fish is soaring worldwide and it appears unlikely that the increasing demand can be met through increased natural harvests as many of the oceans and natural freshwater fisheries are being harvested to their limit. Aquaculture, therefore, remains the last hope for providing enough fish for the world, but with limited land and water space. Aquaculture biotechnology, therefore, has come to have a key role to play as it can make a great contribution to improving aquaculture yields. The application of biotechnology to various production systems does not come without its negative impacts but even still, the merits far outweigh the associated concerns because the techniques are constantly being developed thereby reducing the negative impacts thereof. Therefore, there is need to adopt biotechnological practices if the world is to stand any chance of achieving food security.
